The Band of the Fighting Irish is the marching band of the University of Notre Dame. Over 300 members of the band represent nearly every field of study, including students from across the United States and from overseas. The Band of the Fighting Irish comprises students from the University of Notre Dame, Saint Mary’s College, and Holy Cross College. Founded in 1845, it is the oldest university marching band.

With nearly 400 members each year, the band features nine main sections: trombones, drumline, piccolos, clarinets, saxophones, faltos (mellophones, or f-alto horns), baritones, basses, and trumpets. Each instrument provides a vital timbre that contributes to the unique sound of the Notre Dame Band. 

The band has a 10th section which consists of the band managers. These students help with the day-to-day logistics including moving equipment, assisting directors/band members, crowd control, and everything that helps the band run.
